QBY high viscosity diaphragm pump is available for conveying various corrosive liquids, mediums with particles, high viscosity, volatility, flammability, and highly toxicity, as well as special liquids such as ceramic glaze slurry, fruit pulp, glue, and temporary tank drains. It is a positive displacement pump that combines the advantages of self-priming pumps, submersible pumps, slurry pumps, and other delivery pumps, including stable fluid delivery, strong self-priming ability, low viscosity of the delivered fluid, low vibration, and low noise.
Product Details:
Each of the machine’s two symmetrical working chambers is equipped with an elastic diaphragm, and the two diaphragms are connected via a connecting rod. As compressed air enters the distribution valve through the pump’s air inlet fitting, it is directed into one chamber, causing that chamber's diaphragm to move while the gas in the other chamber is expelled. When the stroke reaches its end point, the diaphragm's reciprocating motion changes the volume of the working chambers, forcing the two ball valves to open and close alternately and enablingcontinuous suction and discharge of liquid.

Application:
1. It can be used for the treatment of sewage and waste oil in drains and sewers.
2. This diaphragm pump can be used to transport naphthenic acid, sodium sulfite liquid and benzene.
3. It can convey all kinds of highly toxic, flammable and volatile liquids, as well as all kinds of strong acid, alkali and corrosive liquids.
4. The gas residue and acidic water at the bottom of refineries, which need to be centralized, our diaphragm pumps can be used to transport these waste liquids.
5. In the petroleum refining process, oil often needs to be poured, loaded and sampled temporarily, in order not to contaminate the normal pipeline, diaphragm pumps can be a temporary substitute to get the job done quickly and easily.
Advantage:
1. The air-operated diaphragm pump's valve structure eliminates traditional valves' “O” ring and column valve structure. It adopts three-way pilot type, which removes valve sticking points and pump-stopping phenomenon.
2. Designed with a simple air reversing valve, expensive downtime costs due to shutdowns can be avoided. Replacement of air-reversing valve components eliminates the need to disassemble fluid components.
3. It can provide the correct reversing signal to avoid stoppage, and the reversing is more rapid, so that the pump flow is large, the conveying performance is good, the pulse is small, and the flow is stable.
4. The slider inside the valve is made of durable material that is not easily damaged, realizing a smooth air path and flexible direction change.
5. Aluminum parts are otherwise treated to resist corrosion caused by unclean air.
